PCO-7111 Series Laser Diode Driver Module
Precision Pulse Control
The PCO-7111 series consists of multiple compact pulsed laser diode driver modules. The modules are designed to provide extremely fast high-current pulses for driving laser diodes in range finder, LIDAR, atmospheric communications and other applications requiring highcurrent nanosecond pulses.
The PCO-7111 has a fixed pulse width typically 5 ns - 10 ns.
Laser Diode Connection
Mounting pads are provided for mounting the laser diode directly to the module. The four-hole pattern accepts TO- 18, TO-5, TO-52, 5.6 mm, and 9 mm packages.
To facilitate additional packages and mounting preferences, two solder pads are provided at the end of the board for laser diodes mounted on-axis to the driver. Alternately, low-inductance stripline cable can be soldered to the pads and connected to a remotely-located diode.
System Operation
Output current is controlled with the voltage at the highvoltage input. The frequency is controlled via gate pulses at the trigger input.
A current monitor output is provided to observe the diode current in real time with an oscilloscope.
